You're correct it is 3-4. Sorry about that. Anyone have any idea what could cause this. The shop wants $130 to diagnose the problem plus the cost to fix it. If it just a loose wire or something stupid like that I would like to look into it myself but don't know where to start.

It relates to the RF passenger seat belt retractor assembly, which has a pretensioner on it (an air bag charge) that fires in an accident to cinch the seat belt into the lock position. The diagnosis requires the factory scan tool and some other special tools to diagnose.

There is a code 4-3 by the way.
4-3- Restraint System- Impact Sensor Fault (Driver Side Communication Fault)
